So that's how they did it British outbred by Anglo-Saxon 'apartheid'

The Anglo-Saxons who conquered England in the fifth century set up a system of apartheid that enabled them to master and outbreed the native British majority, according to gene research published on Wednesday.

In less than 15 generations, more than half of the population in England had the genes of the invaders, investigators say.

"The native Britons were genetically and culturally absorbed by the Anglo-Saxons over a period of as little as a few hundred years," said Mark Thomas, a University College London biologist.
